Provided are an infrared thermometer (100) and a forehead temperature correction and measurement method. The infrared thermometer (100) comprises a temperature sensor (20), a corrector (30), a processor (50), and a display apparatus (40), wherein the temperature sensor (20) is used for measuring the actual temperature value; when entering a correction mode, the corrector (30) respectively records the actually measured values, i.e. an ear temperature value and a forehead temperature value; when entering a forehead temperature measurement mode, the processor (50) generates a body temperature value by means of the actually measured forehead temperature value and a forehead temperature correction value; and the display apparatus (40) can display the body temperature value. By means of the infrared thermometer (100) and the forehead temperature correction and measurement method, accurate measurement of the forehead temperature can be realized.
